WILLIAM GATES, OF NEW HAVEN, CONNECTICUT, ASSIGNOR OF ONE-HALF TO ALBERTL. BABCOCK, OF SAME PLACE.

LATCH FOR CARRIAGE-DOORS.

SPECIFICATION forming part of Letters Patent No. 258,291, dated` May 23,1882.

Application filed August 24, 1881. (Model.)

.To all whom it may concern Be it known that I, WILLIAM GATEs, a citizen4of the United States, residing at New Haven, in the county of New Havenand State of Connecticut, have invented certain new and usefulImprovements in Latches for Carriage- Y Doors; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, in which- Figure 1` isa side elevation of my invention; Fig. 2, a similar view, showing theinterior construction; Fig. 3, a detail view of the back plate; Fig. 4,a detail view of the spring, and ilgt, 5 a similar view of a portion ofthe latch- The present invention has relation to certain new and usefulimprovements in that class of leverlatches for carriages in which thelatch-bolt is operated by an upright lever, pivoted at its lower end tothe latch-plate, and connected to the bolt by an extension or armlocated between two projections on the rear end of the bolt, whereby thebolt is moved outward by the lever and inward by the usual mainspringand other attachments usually employed. t

*.Lo the above class of latches my improvements are designed to apply;and the object thereof is to improve the construction of the operatingparts, especially the lever which operates the latch-bolt, said objectsbeing attained by the construction substantially as shown in thedrawings and hereinafter described.

vIn the accompanying drawings, A represents the latch-plate, havingsuitably connected thereto a back plate, B, to retain the latchbolt andoperating-lever in position. The plate B, upon its inner surface, has arecess, n, for receiving a flat bow-spring, w, as shown in Figs. 3 and4, said spring bearing against the lever D to prevent its rattlingagainst the plates A B.

The latch-bolt E, with elongated slot c, projection g, spindle-hub t',having follower h, stop f, and mainsprng H, are all of the ordinaryconstruction, and commonly in use in the bent lower end toward the backor rear of the latch-case to that extent that the upper end of the leverwill rise in its movement to operate the latch-bolt E. In pivoting thelower end of the lever D to one side or away from a vertical linedescribed by the lever and its handle increased power'is obtained and amore perfect operation of the latch-bolt.

To the rear end of the latch-bolt E is an upright extension, F, having around-faced bearing, a, for a curved recess, o, on the rear edge of thelever D, the latter also having a shoulder, p, which comes against astop, f.

The coiled spring H, or the mainspring,77 as it is termed, has its endbearing against a shoulder, m, on the inner face of the latchbolt, andbetween said shoulder and ashoulder, n, the lever D is located. As theupper end of the leverD rises as it is moved, the handle thereof may beplaced so as to come against or even with the frame in the carriage-doorin which the sash is placed, thereby making a great improvement inappearance.

By pivoting the lever D at its lower end and curving it, as shown, alsoproviding the latch-bolt E with the extension F, having the curvedbearing a, for the recess o of the lever, the latter operates thelatch-bolt with the least possible movement of its upper end, besidesbeing more effective in its operation.

The stop j', together with the shoulder p on the lever, removes thestrain from oft' the bolt and lever when stationary.

The projection g, instead of extending down from the under side of thelatch-bolt, as has usually been the custom, projects or extends aboveit, the spindle-hub being also located above the latch-bolt instead ofbelow.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is 4 In a lever-latch for carriages orother vehicles, the combination, with the latch-bolt E, having theupward extension g, and extension F, with curved bearing a, of theoperatingleverD, curved at its lower end, as shown, and pivoted to theplate A, and having the curved recess o, constructed and arranged tooperate substantially asV and for the purpose set forth.

WILLIAM GATES.
